* Note: a separate listing for Hispanic is not included because the US Census Bureau considers Hispanic to mean persons of Spanish/Hispanic/Latino origin including those of Mexican, Cuban, Puerto Rican, Dominican Republic, Spanish, and Central or South American origin living in the US who may be of any race or ethnic group (white, black, Asian, etc.); about 15.1% of the total US population is Hispanic.

Immigration has contributed to many of the economic, social, and political processes that are foundational to the United States as a nation since the first newcomers arrived over 400 years ago. After brushes with immigration reform that began in 2001 and continued in 2006 and 2007, the United States seems to be on the threshold of overhauling the legal immigration system in the most substantive way since 1965. This article provides a comprehensive overview of major legislation and events affecting U.S. immigration throughout history, legal and illegal immigration flows, postrecession immigration trends, and more.

While many countries are increasing engagement with their diasporas, U.S. policy has chiefly focused on U.S.-based diasporas from other countries, despite its own estimated overseas population of 7.6 million. This feature explores results from a survey of more than 1,400 U.S. citizens and 140 former citizens living abroad, many of whom are critical of limited U.S. government engagement with them even as restrictive financial reporting regulations have been imposed.

With more than 1.8 million immigrants living in the United States, the Philippines was the fourth largest country of origin in 2013. Filipino immigrants stand out from other top immigrant groups with their unique historical experience as former nationals due to U.S. annexation of the Philippines in 1899, close historic ties to the U.S. military, and prevalence in health-care professions.

In 2013, more than 25 million people in the United States reported limited English proficiency (LEP), an 80 percent increase since 1990. The LEP population, the majority of which is immigrant, is generally less educated and more likely to live in poverty than the English-proficient population. This Spotlight explores key indicators of the LEP population, both U.S. and foreign born, including geographic distribution, language diversity, and employment.

As legal challenges continue to impede President Obama's deferred action programs to protect millions of unauthorized immigrants from deportation, it is becoming increasingly clear that the window of opportunity for implementation before the 2016 election is growing ever narrower. Even as advocates continue mobilizing immigrants to apply, attention is shifting to other new policies announced by the president last November.

Immigration to the United States from the Middle East and North Africa (MENA) region has increased in recent years, rising to a total population of 1.02 million in 2013. Immigrants from the region come from a diverse range of countries and cultures. This data Spotlight delves into the variations among MENA groups on key socioeconomic indicators, from geographic distribution and language proficiency to employment, immigration pathways, and naturalization.

Mexico has lost its long-held status as the top source country of new immigrants to the United States, dropping to third place behind China and India. This historic shift is remarkable for the rapid decline in Mexican inflows combined with a steady rise in Asian immigration, largely through high-skilled visa programs. This Policy Beat explores the reasons behind these trends and their potential impact on U.S. demographics.

Indian immigrants represent the second-largest origin group in the United States, accounting for 4.7 percent of the total foreign-born population. Generally high-skilled and highly educated, more than half of Indian immigrants have arrived since 2000 and largely attain green cards through employment-based pathways. Indians account for 70 percent of H-1B petitions and are the second-largest group of international students in the United States.

The H-2B visa allows U.S. employers to bring in foreign workers to temporarily fill low-skill nonagricultural jobs across a wide range of states and industries. A series of recent legal challenges has exposed the presence of fraud and abuse, while stripping the program of its regulations and raising uncertainty about its future. This Policy Beat examines the implications in the debate surrounding temporary worker programs.

Cuban immigrants are afforded a special place in U.S. immigration law, with most able to gain permanent residency after one year in the country. Following a history of surges in maritime migration, more than 1.1 million Cuban immigrants resided in the United States in 2013, accounting for about 3 percent of the total foreign-born population. This article explores key characteristics of Cubans in the United States, including educational attainment, income, and more.

Immigrant women constitute a varied and dynamic population in the United States with 51 percent or 21.2 million of the country's total foreign-born population. Examining key gender-based socioeconomic indicators from origin and fertility to educational attainment and immigration status, this Spotlight raises implications for sending and receiving countries, with respect to labor opportunities, family structure, gender roles, and more.

U.S. media coverage of immigration has hindered effective policy reform for years, a trend which has been exacerbated by the recent transformation in the ways Americans get their news. This has conditioned and even distorted public perceptions by portraying a largely gradual, orderly, and legal phenomenon as chaotic, criminal, and controversial.

Information and technology are centerpieces of a new border architecture that seeks to respond to the competing demands of facilitating mobility and managing cross-border risks while remaining cost-efficient and respectful of rights and privacy. This report shows how governments must approach border management systems to ensure properly balanced development.

Recent developments in the United States (including the 2008 elections and shifts in organized labor’s stance on immigration) have created new openings for comprehensive immigration reform, possibly including a path to legal residence and citizenship for illegal immigrants. But the author argues that the extent of this opening may be overstated by some advocates.

The number of U.S. residents deemed Limited English Proficient (LEP) has increased substantially in recent decades, consistent with the growth of the U.S. foreign-born population. This brief offers analysis on the number, share, growth, and linguistic diversity of LEP individuals in the United States from 1990 to 2010 at the national, state, and metropolitan-area levels.

While English Language Learner (ELL) students are spread throughout the United States, their density, or the share they represent of total public school enrollment, varies greatly by state. This fact sheet, drawing upon data from the U.S. Department of Education, examines the states and districts with the highest shares and populations of ELL students and offers a detailed breakdown of some key statistics.

The 1986 Immigration Reform and Control Act (IRCA) was the first legislative attempt to comprehensively address the issue of unauthorized immigration. The bill included sanctions against employers for the hiring of undocumented migrants, more robust border enforcement, and an expansive legalization program that was unprecedented.

This policy brief examines and reflects upon lessons learned from the last major attempt to resolve the problem of illegal immigration under the Immigration Reform and Control Act of 1986. Arguing that stable reform will require three “E”’s— enforcing immigration laws effectively, expanding visas, and earning legal status —it also offers recommendations for immigration policymaking and management.

Slightly more than 2.1 million unauthorized immigrant youth and young adults could be eligible to apply for legal status under the 2010 DREAM Act, though historical trends indicate that perhaps fewer than 40 percent would obtain legal status because of a variety of limitations. This policy brief offers detailed estimates of potential DREAM Act beneficiaries.

It takes a detailed look at how this legislation will affect document issuing agencies, state budgets, and the employment verification system, in addition to immigrants and citizens.

Repealing birthright citizenship for U.S.-born children of unauthorized immigrants, a step discussed in some circles as a means to reduce illegal immigration, would significantly increase the size of the unauthorized immigrant population in the United States, from 11 million today to 16 million by 2050, this brief reveals.

This briefprovides a historical overview of various attempts at implementing workplace enforcement in the United States before arguing in favor of a process not unlike credit-card verification that allows employers to swipe a card at the point of hire and receive a response in real time from the Social Security Administration informing them whether an employee is authorized to work in the United States.

This brief argues that an essential first step to any type of U.S. legalization must be a registration process that rapidly identifies, screens, and processes potential applicants. The government could successfully administer a large-scale legalization only with a well-crafted bill, sufficient funding, an unprecedented mobilization of public and private stakeholders, and intensive planning.

Thisreport provides an overview of United States border enforcement throughout the 20th century, highlights how it has changed since the passage of the Immigration Reform and Control Act nearly two decades ago, and further examines its unprecedented expansion in the aftermath of 9/11. The author concludes with a set of policy questions.

This policy brief shows that more unauthorized immigrants in the United States have been legalized through population-specific and registry programs than through the 1986 Immigration Reform and Control Act general legalization provisions.

This volume, which brings together research by leading economists and labor market specialists, examines the role immigrants play in the U.S. workforce, how they fare in good and bad economic times, and the effects they have on native-born workers and the labor sectors in which they are engaged. The book traces the powerful economic forces at play in today’s globalized world and includes policy prescriptions for making the American immigration system more responsive to labor market needs.

Securing the Future seeks to define what policymakers and scholars mean by integration while attempting to sketch the contours of U.S. integration policy. The volume reviews evidence of immigrants’ integration by examining the progress of the second generation, as well as trends in education, health, the workforce, and citizenship.

This interdisciplinary volume examines the health, well-being, school readiness, and academic achievement of children in Black immigrant families (most with parents from Africa and the Caribbean)—a population that has had little academic attention even as it represents an increasing share of the U.S. Black child population.

This edited volume develops a pragmatic approach to the engagement of highly skilled members of the diaspora for the benefit of their countries of origin. The book, edited by a World Bank senior economist, is based on empirical work in middle-income and high-income economies.

Over the past four years, the United States has resettled far fewer refugees than it did in the 1990s. The decline has stemmed partly from post-9/11 security measures. But this book explains other, deeper reasons, deriving from changes in how and why refugees move, how asylum states receive them, and the world community's response. It also suggests steps to restore the program and better address real refugee needs.

The book focuses on three case studies: the United States, the United Kingdom and Germany. The volume includes chapters analyzing public opinion and media coverage of immigration issues in each country. Additional chapters propose strategies for unblocking opposition to thoughtful, effective immigration-related reforms.

This volume, by a former senior counsel to the 9/11 Commission, argues that the U.S. approach to immigration and border security is off-kilter and not keeping pace with the scope and complexity of people’s movement around the world, nor with expectations regarding freedom of movement.

This edited volume rigorously assesses the 1996 U.S. welfare reform law, questions whether its immigrant provisions were ever really necessary, and examines its impact on legal immigrants’ ability to integrate into American society.
